More than in the explanation, described brake pedal sensor 2 detects the action of the brake pedal 1 that is configured in actuation unit, and control setup 20 exported, specifically, detect the amount of entering into of this pedal, operational tons such as the timing that begins to trample and the speed of entering into, and detection signal outputed to control setup 20.In control setup 20, come the oil pressure circuit 22A of the described foot-operated brake in the brake system that control vehicle possesses, the work of 22B based on this detection signal.
Thereby described vehicle sensors 2 is devices that the speed of a motor vehicle of detection industrial vehicle is exported to this detected value control setup 20, for example constitute, utilize vehicle velocity signal with the rotation number pulse to be input to the device etc. of control setup 20 by the tachogen that is arranged on final reductor etc.
Described accelerator open degree detecting sensor 5 detects by the entering into of the Das Gaspedal 4 of driver's operation, and exports to control setup.In control setup 20, store the throttle amount of entering into and corresponding with the throttle amount of entering into and should export to the output valve of engine apportioning valve etc. (omitting diagram) explicitly.Control setup 20 according to the detection signal from accelerator open degree detecting sensor 5, is adjusted the output of the apportioning valve of flow regulating valve (throttle valve) the control usefulness that offers engine based on this canned data, thus the rotating speed of Control Engine.Described Das Gaspedal 4 is provided in the actuation unit of chaufeur, and is set at the engine speed of expectation.
Described gearshift range detection parts 8 are to detect gearshift scope from 7 inputs of gear shift operation parts (to advance: F, neutrality: N, retreat: R), and to the device of described control setup 20 output gearshift range detection signals.Described gear shift operation parts 7 are the devices that are provided in the actuation unit of chaufeur and are set at the gearshift scope of expectation, use shifter bar (shift lever), shift switch (shift switch) etc.
Described solenoid electric valve 9 is for such control of braking electromagnetic control drg 10 and according to the ON/OFF signal of electromagnet (solenoid) and the valve of switch oil pressure as mentioned above.
Here, the deceleration of the brake system that generally possesses of vehicle when carrying out vehicle ', the foot-operated brake (service brake) that stops etc. and the parking brake of keeping (Parking Brake) that mainly carries out the halted state of vehicle constitute.
Described parking brake be with mechanical type or DYN dynamic mode to the device of vehicle brake activation, have the main body of described master controller installed the type of stopping brake mechanism and the type that independently is provided with the mechanism of stopping brake special use.
In the present embodiment, but such as mentioned above master controller has the structure of electromagnetic control, satisfies when vehicle stops under the situation of defined terms, makes this electromagnetic control drg 10 work automatically.Thereby, when this electromagnetic control drg 10 is to stop under the situation of drg, with the operating system 101 that stops drg 11 irrespectively, apply master control to keep the state continuance of halted state.
Preferably include alarm features 11 in addition in the present embodiment.This alarm features 11 is when carrying out the control of braking of present embodiment, and the parts that the third party of chaufeur or vehicle periphery is given a warning for example, can be enumerated the warning buzzer of output sound or alarm tone or light or extinguish the warning light etc. of lamp.In addition, also be made as when carrying out the control of braking of present embodiment, light the structure of the stoplight stop lamp 12 that vehicle possesses.
According to said structure, carry out control of braking shown in Figure 2 in the present embodiment.
In the vehicle ' process, solenoid electric valve 9 is closed and opens braking relief valve 90, thereby electromagnetic control drg (foot-operated brake) 10 becomes the braking disarm state, and they also become the OFF state under the situation that comprises alarm component 11, stoplight stop lamp 12.Be used to represent that vehicle is below the regulation speed of a motor vehicle Xkm/h of halted state if detect by car speed sensor 3, then really to be considered as be halted state to control setup 20.In addition, if enter into the detected predefined setting-up time Y of signal more than second from the drg of brake pedal sensor 2, then solenoid electric valve 9 is switched to be made as and open and will brake relief valve 90 and switch and be made as the control signal of closing, and carry out the control of braking of lasting braking mode till braking is removed by control setup 20 output.In this control of braking, under situation, they are switched to ON with alarm features 11, stoplight stop lamp 12.
In the braking procedure of described electromagnetic control drg 10, detect by described gearshift range detection parts 8 that expression is advanced or the incoming signal that retreats after, signal as if the ON that enters into by described accelerator open degree sensor 5 detection throttles, then solenoid electric valve 9 is switched and close and will brake relief valve 90 switching control of turning signals, and remove this control of braking by described control setup 20 outputs.Under the situation that comprises alarm features 11, stoplight stop lamp 12, they are switched to OFF.
This moment is preferred, only continue more than the predefined specified time t2 to detect expression gearshift scope be advance or the incoming signal that retreats after, enter into time length for ON of speed change is under the situation more than the predefined specified time t1, to remove described control of braking.
Then, with reference to Fig. 3 and Fig. 4, describe the treatment scheme of above-mentioned control setup 20 in detail.
At first, Fig. 3 represents the treatment scheme of control of braking.To be used to judge that the mark that whether carries out the setting of following processing is called the control of braking mark, described processing be the reflection chaufeur stop/setting out the meaning, automatically carry out the processing (below, be called control of braking) of control of braking.
In Fig. 3, judge that by control setup 20 described control of braking marks whether to be set to ON (S1), be set under the situation of ON, solenoid electric valve 9 is made as to open and will brake relief valve 90 is made as closed condition, thereby in the future the oil pressure of self-pumping 21 offers the hydraulic chamber 103 of electromagnetic control drg 10, thereby electromagnetic control drg 10 becomes effectively (brake activation power) (S2).
On the other hand, when described control of braking mark is set under the situation of OFF, according to control signal from control setup 20, based on described control signal, to brake relief valve 90 is made as and closes and solenoid electric valve 9 is made as unlatching, thereby the oil pressure that comes self-pumping 21 is provided for the oil hydraulic cylinder 104 of electromagnetic control drg 10, and is invalid thereby electromagnetic control drg 10 becomes.
Fig. 4 represents the setting/releasing treatment scheme of control of braking mark.Control of braking mark based on here setting or remove carries out above-mentioned control of braking shown in Figure 3.
At first, below expression is the processing of ON with the control of braking flag settings.
Whether the setting of judging the control of braking mark by control setup 20 is ON (S11), also be not set at ON but under the situation of OFF, judge whether brake pedal detector switch 2 detects the signal (S12) of entering into that brakes at setting-up time X more than second, under the situation that is ON, whether judgement is (S13) below the speed of a motor vehicle of expression halted state by the car speed sensor 3 detected speed of a motor vehicle, when being judged as vehicle is under the situation about stopping, and is ON (S14) with the control of braking flag settings.On the other hand, be under the situation of OFF when brake pedal detector switch 2, perhaps ought not under the situation of vehicle halted state, to return.
Then, below expression is the processing of OFF with the control of braking flag settings.
Whether the setting of judging the control of braking mark by control setup 20 is ON (S11), become under the situation of ON when being set, differentiating by gearshift range detection parts 8 detected gearshift scopes is which (S15) among F (advancing), N (neutrality), the R (retreating).Be to return under the situation of N when the gearshift scope.When the gearshift scope is under the situation of F or R, whether judgement is entered into by accelerator open degree detecting sensor 5 detected throttles is ON (S16), entering into when this throttle is under the situation of ON, is judged as the condition subsequent that satisfies control of braking, is that OFF removes (S17) with the control of braking flag settings.On the other hand, under the situation that does not satisfy above-mentioned condition subsequent, return.
According to such present embodiment, by simple apparatus structure and do not carry out the control that stops/setting out the meaning that numerous and diverse driver behavior just can be used to realize chaufeur, and can improve safety when can improve the operability of chaufeur.
Promptly, in the present embodiment, working as the brake that detects brake pedal 1 more than the predefined setting-up time Y enters under the situation of signal, be considered as chaufeur have stop the meaning, electromagnetic control drg 10 automatically is made as actv. control, even thereby under the situation of vehicle posture shakinesses such as slope, also can keep the halted state of vehicle, improve safety.In addition, enter under the situation of signal, carry out above-mentioned control, therefore can verily reflect the meaning that stops of chaufeur owing to only be set at detecting brake more than the predefined setting-up time Y.
